Here's a shot of the model
And here is the artwork that inspired the sculpt
This model just screams Nurgle to me. You could use this guy as a Chaos Lord, Chaos Sorceror, or evan as a Herald of Nurgle. I just really like the pose and the spikes coming out of the back of the model.
The model costs right at $8 (which is a steal) and is available from Dark Sword's Store and also from Cool Mini or Not's online shop.
